*Aerothermia systems are not only cooling system using hot or cold air, but they can supply hot water and heating in winter and cold water for distribution in the summer. In essence, the Aerothermal or heat pump is a domestic renewable energy generator that uses heat from the air to produce 70% of the energy needed to provide heating (from -25 ° C) or cooling (up to 46 ° C). In addition, the new generation of Aerothermal equipment also allows for heating water. Aerothermal systems can reduce heating bills by 80% compared to electric radiators.
